81. 返回值： 82.

83. 函数成功返回 0 ，失败返回非 0 。 84. 85. 86. 87. 88.

. 例子： 90.

91. 1. 将 C:\\Test.txt 拷贝到 D:\\ 92. 93. 94.

95. SHFILEOPSTRUCT lpsh; 96.

97. ZeroMemory(&lpsh,sizeof(lpsh)); 98.

99. lpsh.hwnd= HWND_DESKTOP; 100.

101. lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;

102.

103. lpsh.wFunc=FO_COPY; // FO_MOVE 则是移动 104.

105. lpsh.pFrom= \"C:\\Test.txt\"; 106.

107. lpsh.pTo = \"D:\\\" 108.

109. if( 0 != SHFileOperation(&lpsh)) 110. 111. { 112.

113. AfxMessageBox(\"复制文件出错,请检查\"); 114.

115. return ; 116. 117. } 118. 119. 120.

121. 2. 删除 D:\\Test.txt 122.

123. SHFILEOPSTRUCT lpsh; 124.

125. ZeroMemory(&lpsh,sizeof(lpsh)); 126.

127. lpsh.hwnd= HWND_DESKTOP; 128.

129. lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;

130.

131. lpsh.wFunc=FO_DELETE;

132.

133. lpsh.pFrom= \"D:\\Test.txt\"; 134.

135. if( 0 != SHFileOperation(&lpsh)) 136. 137. { 138.

139. AfxMessageBox(\"删除文件出错,请检查\"); 140.

141. return ; 142. 143. } 144. 145. 146.

147. 3.重命名 148.

149. SHFILEOPSTRUCT lpsh; 150.

151. ZeroMemory(&lpsh,sizeof(lpsh)); 152.

153. lpsh.hwnd= HWND_DESKTOP; 1.

155. lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;

156.

157. lpsh.wFunc=FO_RENAME; 158.

159. lpsh.pFrom= \"D:\\Test.txt\"; 160.

161. lpsh.pTo = \"D:\\Test2.txt\"; 162.

163. if( 0 != SHFileOperation(&lpsh)) 1. 165. { 166.

167. AfxMessageBox(\"重命名文件出错!\"); 168.

169. return ; 170. 171. } 172.

173. 注意事项：

174. 参数pTo、pFrom必须是以 双0 结束的，原文为： 175. pFrom 176.

177. Pointer to a buffer that specifies one or more source file names. Multiple names must be null-separated. The list of names must be double null-terminated.

178.

179. a.如果是直接赋值：

180. WCHAR strSrc[MAX_PATH] = _T(\"g:\\\\123\"); 181. WCHAR strDst[MAX_PATH] = _T(\"g:\\\\456\"); 182. 这样就可以成功编译。 183.

184. b.如果pTo、pFrom从CString获得，则：

185. WCHAR SrcFolder[MAX_PATH],DestFolder[MAX_PATH]; 186. wcscpy_s(SrcFolder, Source); 187. wcscpy_s(DestFolder,m_Path); 188. SrcFolder[wcslen(SrcFolder) + 1] = 0;

1. DestFolder[wcslen(DestFolder) + 1] = 0;（其中，Source与m_Path是在其他地方获取的值）

190.

191. 造成这种差异的原因是：CString在结尾并没有\"\\0\"，所以需要我们添加。
